‘Penstemon’ plant named ‘Cha Cha Cherry’

ABSTRACT

A new and distinct cultivar of  Penstemon  plant characterized by medium size red flowers in dense clusters, long bloom time, attractive deep purple seed heads, a compact, upright, well branched habit, with multiple crown from the base, clean-looking, deep green, attractive foliage, and excellent vigor.

Botanical denomination: Penstemon hybrid.

Variety designation: ‘Cha Cha Cherry’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofPenstemon, given the name, ‘Cha Cha Cherry’. Penstemon is in the familyPlantaginaceae (formerly Scrophulariaceae). This plant originated in acontrolled breeding plan to create a compact, upright, medium size,multiflowered series. The exact parents are unknown, unnamed proprietaryplants. This cultivar was selected for its compact growing habit, mediumsize flowers in dense clusters, long flowering time, vigor, and cleanattractive look. It is an ideal plant for a sunny border in full sun.

Compared to plants of Penstemon Arabesque™ Red hybrid, an unpatentedseed strain, the new cultivar is more vigorous, flowers earlier, and hasmore numerous flowers with no white eye rather than a white eye.

Compared to Penstemon ‘Garnet’, an unpatented plant, the new cultivarhas an upright habit rather than somewhat floppy, larger, more numerousflowers that are red rather than rose red, and larger leaves.

Penstemon ‘Cha Cha Cherry’ is uniquely distinguished by its:

-   -   1. medium size red flowers in large dense clusters,    -   2. long bloom time,    -   3. compact, upright, well branched habit, with multiple crowns        from the base,    -   4. attractive deep purple seed heads,    -   5. clean-looking, deep green, attractive foliage, and    -   6. excellent vigor.

The new variety has been reproduced only by asexual propagation(cuttings and micropropagation). Each of the progeny exhibits identicalcharacteristics to the original plant. Asexual propagation by cuttingsand micropropagation using terminal and lateral shoots as done in Canby,Oreg., shows that the foregoing characteristics and distinctions cometrue to form and are established and transmitted through succeedingpropagations. The present invention has not been evaluated under allpossible environmental conditions. The phenotype may vary withvariations in environment without a change in the genotype of the plant.
